. Slide the wavelength bar to the highest possible value. What happens to the diffraction pattern? Now slide the wavelength to the lowest possible value. What happens to the difaction pattern? Based on this, what do you predict about the relationship between the wavelength of the light and angle between the minima in the diffraction pattern? Is this what equation 1 would predict? Watch the experimental setup in the dark grey region of the screen. Are there more rays of light (diffraction maxima) visible for lower or for higher wavelengths? . Return the wavelength to 600 nm (you can type it in the box to get it correct). Now slide the slit width bar to change the value for a from small to large. What happens to the diffraction pattern? Based on this, what do you predict about the relationship between the slit width and angle between the minima in the diffraction pattern? Is this what equation 1 would predict? Watch the experimental setup in the dark grey region of the screen. Are there more rays of light (diffraction maxirna) visible for lower or for higher slit widths? . Now you will need to set your wavelength and slit width to the values shown in Table 1 below, and record the position of the rst minimum (Bap), which is shown in the "Minima" drop down dox in the green region of the screen. (Notice that if you pull on this drop down box, you can also see the locations of higher order minima). Use equation 1 to calculate the theoretical position of the minimum (9111:0qu Do they agree? Table 1: Experimental Observations for Single Slit Diffraction . In trials 1-3 and 4-6, the slit width has been altered with the wavelength constant. What has happened to the angle between the minima as the slit width increased? Does this agree with your results in step 2? . Now compare the results for trials 1 and 4 in Table 1. These trials have the same slit width, but the wavelength in trial 4is twice that in trial 1. The same relationship is true for trials 2&5, and 3&6. What do you notice about the effect of doubling the wavelength on the separation of the minima
